Plato used the work schema to mean important rather than exhaustive information. This property summarisation is the primary characteristic of a schema. A schema acts as a reduced description of important aspects of an object or an event. David Rumelhart and Andrew Ortony, in their essay “The Representation of Knowledge in Memory”, undertake a detailed theory of schema that draws on the disciplines of both cognitive psychology and computer science. They put forward four qualities of schemas. Schemas have variables. Schemas provide a framework into which new information from the environment is integrated. Schemas can embed. In other words, the schema that constitutes a framework for understanding the concept airplane may contain a schema for representing information about wings or even about the process of travel. Schemas represent knowledge at many levels of abstraction. For example, schemas can represent information about objects in the environment, but they can also represent information about the way objects interact of the nature and structure of events. Schemas represent knowledge rather than definitions. Schemas are essentially “encyclopedia” rather than “definitional”.
